Abstract: An audio system includes one or more loudspeaker cabinets, each having loudspeakers. Sensing logic determines an acoustic environment of the loudspeaker cabinets. The sensing logic may include an echo canceller. A low frequency filter corrects an audio program based on the acoustic environment of the loudspeaker cabinets. The system outputs an omnidirectional sound pattern, which may be low frequency sound, to determine the acoustic environment. The system may produce a directional pattern superimposed on an onmidirectional pattern, if the acoustic environment is in free space. The system may aim ambient content toward a wall and direct content away from the wall, if the acoustic environment is not in free space. The sensing logic automatically determines the acoustic environment upon initial power up and when position changes of loudspeaker cabinets are detected. Accelerometers may detect position changes of the loudspeaker cabinets.

Abstract: Ein Verfahren zum Verarbeiten eines Tonprogramms durch ein Wiedergabesystem, bei dem ein virtueller Mittenkanal aus dem Tonprogramm extrahiert wird und eine Dynamikbereichskomprimierung und eine Anhebung angewendet werden, um einen komprimierten virtuellen Mittenkanal zu erzeugen. Dieses wird dann zum Erzeugen eines Lautsprechertreibersignals verwendet. Es werden auch andere Aspekte beschrieben und beansprucht.

Abstract: Implementierungen der gegenständlichen Technologie stellen Systeme und Verfahren zum Bestimmen, ob ein Benutzer einer Audiovorrichtung, die in einem Betriebsmodus mit Geräuschunterdrückung betrieben wird, unterbrochen werden soll, bereit. Zum Beispiel kann der Benutzer wünschen, durch einen oder mehrere vorher bestimmte Kontakte, die an einer zugehörigen elektronischen Vorrichtung als unterbrechungsberechtigte Kontakte identifiziert werden, oder dadurch, dass eine Person ein zugewiesenes Schlüsselwort zum Benutzer sagt, unterbrochen zu werden.
